 ## Highlights
 
-- **Surgical Code Edits:** Gemini models are now steered to prefer the `edit`
-  tool for surgical modifications, leading to faster and more precise code
-  updates.
-- **Session Portability:** Introduced features to export active sessions to
-  files and import them later via a CLI flag, allowing for easier session
-  sharing and resumption.
-- **Adaptive Token Estimation:** A new adaptive token calculator provides more
-  accurate content size measurements, optimizing context window usage and
-  reducing API overhead.
-- **Improved UI Rendering:** Core tools now utilize native `ToolDisplay`
-  properties, fixing various UI rendering issues and improving the experience in
-  ACP-compliant IDEs.
-- **Enhanced Agent Architecture:** Introduced `LocalSubagentProtocol` and
-  `RemoteSubagentProtocol` behind a unified `AgentProtocol`, laying the
-  groundwork for more complex multi-agent interactions.
+- **Caretaker Services:** Introduced a new caretaker triage worker including
+  core foundational modules, main worker execution loops, egress action
+  publishers, and octokit GitHub Action handlers.
+- **Robust File Editing:** Core tools like `write_file` and `replace` now bypass
+  LLM corrections for JSON and IPYNB files to ensure accurate and direct file
+  modifications.
+- **Plan Mode Improvements:** Simplified plan mode write policies to natively
+  support writing to relative paths, enhancing project directory navigation.
+- **Enhanced Account Visibility:** Improved clear user-facing messages when the
+  user account does not have a Code Assist tier, and enriched shared project
+  quota limit errors with setup instructions.

 ## Highlights
 
-- **Context Simplification:** Completed major architectural work to simplify and
-  optimize how the agent manages and processes session context.
-- **A2A Usage Metadata:** The Agent-to-Agent (A2A) interface now exposes
-  detailed usage metadata, providing better visibility into resource
-  consumption.
-- **Improved Routing:** Updated default auto-routing logic and added bypasses
-  for certain routing classifiers to prevent orphaned function response errors.
-- **Terminal Stability:** Fixed several issues affecting terminal environments,
-  including Termux relaunch loops and PTY resize errors.
-- **Security & Fixes:** Strengthened MCP list security and addressed issues with
-  session resumption and PTY environment signals.
+- **Caretaker LLM Triage Orchestrator**: Implemented the LLM triage orchestrator
+  and container build configuration to support caretaker triage workflows.
+- **Enhanced Workspace Trust & Sandbox Hardening**: Aligned macOS permissive
+  Seatbelt profiles with the deny-default model and enforced workspace trust and
+  task isolation in the Agent-to-Agent (A2A) server to prevent remote code
+  execution (RCE).
+- **Core Robustness & API Protections**: Mitigated infinite ReAct and prompt
+  injection loops, and prevented 400 Bad Request errors by grouping cancelled
+  tool responses and coalescing consecutive roles.
+- **Robust Credentials & Fallbacks**: Restored the
+  `GOOGLE_APPLICATION_CREDENTIALS` environment variable fallback and
+  sequentially verified cached credentials.
+- **Evaluation Coverage Reporting**: Added a new command to generate
+  comprehensive eval coverage reports.

+
+To help maintainers estimate review effort and keep the PR history clean, this
+workflow automatically tags every pull request with a size label representing
+the total volume of line changes.
+
+- **Workflow File**: `.github/workflows/pr-size-labeler.yml`
+- **When it runs**: Immediately after a pull request is created, synchronized
+  (new commits pushed), or reopened. It can also be triggered manually via
+  `workflow_dispatch` with a PR number.
+- **What it does**:
+  - **Calculates total changes**: Summarizes additions and deletions across all
+    changed files in a single consolidated API request.
+  - **Applies standard size labels**:
+    - `size/XS`: < 10 lines changed
+    - `size/S`: 10-49 lines changed
+    - `size/M`: 50-249 lines changed
+    - `size/L`: 250-999 lines changed
+    - `size/XL`: >= 1000 lines changed
+  - **Updates size tag atomically**: Adds the new correct size label and removes
+    any obsolete size labels in one atomic step.
+  - **Updates/Posts PR size info comment**: Instead of spamming a new comment on
+    every commit push, it updates the existing size labeler status comment
+    inline to keep the PR conversation timeline perfectly neat and clean.
+- **What you should do**:
